The Descriptive Cataloging of Rare Materials (Cartographic), available as a PDF file (direct link), “provides instructions for cataloging rare cartographic materials, that is, cartographic materials of any age or type of production receiving special treatment within a repository.” This is a substantial, technical document (364 pages), mainly of interest to librarians with rare and old maps under their care.

With an increased focus on the security of rare cartographic materials, DCRM(C) addresses the need for a stand-alone set of rules that covers the treatment of atlases, maps, and globes, both printed and manuscript, including the analysis of cartographic works in books or other resources, and can be used by any institution that houses these materials. The creation of a standard eliminates the need for each institution to develop extensive local practices for the treatment of rare cartographic works, and makes it possible for institutions with smaller collections to benefit from both the sophisticated tradition of rare materials cataloging and the awareness of the cartographic community of the particular qualities of our materials.
